* Millennium High School's specific requirements: Check Millennium High School's website or contact their admissions office directly. They may have specific deadlines for submitting test scores as part of the application process. Some schools require scores for admission, while others may consider them but aren't mandatory.
* Your own testing timeline: Some students prefer to take practice tests earlier to identify areas for improvement. Others wait until they feel ready for the "real" test. Consider your academic strengths and weaknesses and when you think you'll perform your best.
* Your application deadlines: If you're applying to Millennium High School for a specific year, work backward from the application deadline to determine when you need to take the tests and allow time for score reporting.
In short, you should contact Millennium High School directly to get the most accurate and up-to-date information on their testing requirements and deadlines.
